HBsAg will be detected in an infected person’s blood an average of 4 weeks (range: 1–9 weeks) after exposure to the virus.
Q. What does reactive anti-HBs mean?
■ Anti-HBs [sometimes written as HBsAb] (antibody to hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is immune to hepatitis B infec- tion, either from vaccination or from past infection.

Q. What does non reactive Hep B titer mean?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.
Q. What is IgM anti-HBs?
Anti-HBc (IgG and IgM) antibodies are the body’s first response to a hepatitis B virus (HBV) infection. These antibodies are directed against a portion of the HBV called the core. IgM anti-HBc antibodies appear shortly after the symptoms and appearance of HBsAg.
Q. What does low Anti-HBs mean?
Anti-HBs greater than 10-12 mIU/mL: Protected against hepatitis B virus (HBV) infection, either from vaccination or successful recovery from a previous HBV infection. Anti-HBs less than 5 mIU/mL: Negative for HBV infection, but susceptible and hence requires vaccination.
Q. What is HBsAb?
Antibody to hepatitis B surface antigen (HBsAb) is the antibody that best correlates with immunity to. hepatitis B virus (HBV).
Q. What is HBs Ag test?
Test for Active or Chronic Hepatitis B Hepatitis B surface antigen (HBsAg) is a blood test ordered to determine if someone is infected with the hepatitis B virus. If it is found, along with specific antibodies, it means the person has a hepatitis B infection.
Q. Is anti-HBs IgM or IgG?
Anti-HBc IgG and IgM appear shortly after the symptoms and onset of the virus surface antigen (HBsAg). IgM arrives first and is then replaced by IgG. Anti-HBc IgG are interpreted in light of clinic factors and the results of other hepatitis B markers, particularly HBsAg and anti-HBs.
